Danfoss Electronic Soft Starters

There are several methods for reducing starting torque and Starting current and the most efficient method is using a solid state soft starter. The heart of the Danfoss CI-tronic™ soft starters is the LTE (Low Thermal Expansion) power chip. This power chip virtually eliminates the effects of thermal expansion which can lead to the generation of "hot spots" and subsequent device failure. This together with the Danfoss one-shot vacuum soldering assembly process, makes the CI-tronic™ one of the most reliable soft starters available.

Covering the power range from 0.1 to 22 kW, the Danfoss MCI soft starters are ideal for a wide range of start and stop applications where smooth operation is required. Use them on pumps, compressors, fans, conveyors, gear or belt driven machinery and countless other types of equipment. MCI is designed for unlimited number of operations per hour and is just as easy to specify and install as an ordinary contactor. Individual adjustable acceleration and deceleration times, up to 60 seconds Initial torque adjustable from 0 - 85% Breakaway function (Kick Start) Universal control voltage: 24-480V ac/dc Automatic detection of missing phases Automatic adaptation to 50/60 Hz LED status indicator Built-in varistor protection Unlimited start/stop operations per hour Optional aux. contacts Compact DIN rail mountable design

Danfoss TCI starting torque limiters are designed for soft starting of 1- and 3-phase AC motors. The TCI unit is easy to install between the motor starter and the motor, and features adjustable ramp-up time and initial torque. Single and three-phase operation Adjustable ramp-up times from 0.5 - 5 seconds Initial torque from 0-85% Built-in varistor protection Unlimited start/stop operations per hour Compact DIN-rail mountable design
